Results for 'catechol':
EXPERIMENT 1
---------------
Cobalt (II) gives a coordination complex with catechol (or is this due
to formation of a cobalt (III) complex with catechol????).
EXPERIMENT 2
---------------
Phenol and its derivatives form highly colored coordination complexes
with ferrous and ferric ions.
EXPERIMENT 3
---------------
Copper gives a coordination complex with catechol, but only in alkaline
environments. This complex is easily oxidized by oxygen from air. Iron
also forms a complex in acidic media, probably by a combined red/coordination
reaction.
EXPERIMENT 4
---------------
A large set of compounds is checked on interaction with concentrated
nitric acid. Many reductors react violently with nitric acid.
EXPERIMENT 5
---------------
Catechol appears to react with nickel (II), giving a coordination complex.
It is unclear, whether this is due to catechol itself or due to an
oxidation product, caused by oxidation by oxygen from air.
EXPERIMENT 6
---------------
Catechol, resorcinol and hydroquinone all are dihydroxy benzenes. When an
ortho-pair (1,2-pair) or a para-pair (1,4-pair) is present, then the compound
is easily oxidized by air in alkaline environment. When a meta-pair (1,3-pair)
is present, such a reaction does not occur.
EXPERIMENT 7
---------------
Catechol forms a coordination complex with vanadyl.
